摘要： An integrated straw and container. The container includes an interior bottom surface and defines an opening near an upper portion of the container. A cap can be placed onto the container to close the container, and then removed to open the container. The straw includes a shape that operates as a spring operates to create two states: a resting or expanded state and a compressed state. In the resting state of the straw, the overall distance from the first end to the second end is greater than the distance from the interior bottom surface of the container to the opening of the container. The straw is placed into the container and the container is sealed forcing the straw into a compressed state. Upon removal of the cap, the straw returns to a resting state in which the upper end protrudes from the container opening.
